The lumped parameter model of heat transfer coupling with double group point reactor model was used to simulate reactivity disturbance for small pressurized water reactor at higher power condition and lower power condition,respectively.
本文采用双群点堆动力学模型耦合传热集总参数模型,分别对小型压水堆高、低功率条件下反应性扰动进行模拟,并与三维仿真模型进行比较。
